T 0 all whom it may concern;

Be it known that l, Jessa T. SPAULDII'EG, a citizen of the United States, residing at Port or "ll improvements in jilailroad lics, of which. the following is specification.

This invention relates to railroad ties, and it has for its object to provide a composite metallic and wooden tie in which anletallic casing is combined with blocks of wood that will serve to directly support the rails; said wooden hlocks being readily removable so as to enable them to be exchangedfornew ones after they have been rendered useless by, W68I' O.f decay.

Further objects or the invention are to simplify and improve the construction and operation. of this class of devices and to provide a tie which will be eminently safe, durable, and practically efficient,

lVith these and other ends in vie'vv which Wiil'readily appear as the nature "of the invention is better understood, the same coin sists inthe improved construction,"and'novel arrangement and combination of parts which will be hereinafter fully described and par.- ticularly pointed out in the clainii. i

in the accompanying drawings has been illustrated a simple. and preferred form of the invention; it being, however, understood that no limitation is necessarily made to the precisestructural details therein exhibited, but that changes, alterations and modificationswvithin the scope of the invention may be "resorted to when desired.

In the drawing, Figure 1 1s a side eleva tiOD of a railroadtie constructed in accord- ."flance with the invention.

' View; Fig. 5 is a transverse sectional view taken on the. plane indicatedjby the line o t) in Fig. 2.- 45

Corresponding parts in the several figures are denoted by like characters of reference.

The casing ofthe improved railroad tie is made of sheet metal or plate metal, preferably steel said plate being'preferably about one half inch in thickness. Asuitablefblanlf is eat or stamped. fromthe sheet or plate, said blankbeing bent to form a box-like shell or casing including-the bottom 1, side walls ii -3,16% latter which are overlapped walls 2-2' and end being formed by flaps and connected to 'ether h fastening w m J in i will not contact with the rail flanges,

such asrivets ll. 'Ihe side walls 2-2 are provided adgacent to the ends of the casing w th tlmg'es 5 5 extending inwardly over the casing; the flanged portions of the side walls are provided with notches 6 which extend into the side walls from the upper edges'ot the latter for a purpose which will presently he made apparent. v

Hail supporting blocks 7 which are made of vwood, and Which'are made of a cros's sectional area; approximately corresponding to that of the standard railroad tie ordinarily employed, are fitted in the ends of the'tie casing; said blocks being of a length which will enable them to he introduced between the side walls of the casing intermediate the flanged ends of said. side Walls, after which they may he slid or moved lengthwise within the casing to the ends of the latter Where they abut upon-the end walls 3; said blocks being secured in position against upward displacement by the flanges 5 and agains endwise displacement by means'of bolts 8 extending transversely through said blocks and through apertures formed for their reception in the side walls of thecasing. The

central portion of the casing is preferably pressed downward to form a depressed portion 9 which is provided withapertures 10 through which Water that enters the tie casing may drain out. Q

. The rails, one of which has been shown at 11, are supported upon the blocks 7, said rails being disposed in the notches 6 which,

as hereinbefore stated, are cut of such a depth that the metallic portion of the casing the latter being supported exclusively upon the wooden blocks which possess the requisites of elasticity and resiliency to the desired degree, and which for Well known reasons form rail supports that are more efficient and desirable than the comparatively unyielding metal of the casing. The rails may he secured upon the blocks, in the customary manner, by means of spikes 12; and the rail may thus be readily detached and renewed in the customary manner without involving the necessity of tools orjspecially skilled labor other than thztwhich is usually employed in the const-ructidn and repairs of railroads. The improved railroad ties may be placed in osition in the customary manner, and the ro'adhed may he hallasted and tamped as ulsual. l filling of sand, gravel, dirt, ce-

or suitable material may, it desired. be intlwliurml into the casing between I center of the casing to form :1 clepressir.) n, the blocks 7: but this is entirely optional I said bottom being formed with openings in with those using the improved tie. ihq depression portion.
